• Movie Poster Colors Over Time

  - by Jason Fitzpatrick

  This spectrograph-like image records tens of thousands of movie posters over the course of a century, showing a steady shift towards posters that emphasize black, purple, and blue color tones. It’s a neat look at how the color tastes of an entire industry shift over time. Vijay Pandurangan had a disagreement with a friend about whether or not movie posters were becoming darker/bluer over time. Rather than simply agree to disagree, he whipped up a piece of code that downloaded and analyzed thousands of movie posters proving that, in fact, there was a slow and steady shift towards darker and bluer posters. Hit up the link below to see the interactive version (and larger!) version of his infographic as well as his explanation of the process and the source code.

• HackingSilverlight Code Browser

  So sometime ago I had been working on a sample browser for all the different samples I had used for hackingsilverlight and for blog posts. After awhile with all the jumping around between projects, and my failing memory I found I needed a quick easy way to remember all the code clips I used often. For me I needed something like a rola-deck for code so after taking my toys and leaving the sandbox as it were regarding the book HackingSilverlight between projects for the 5 minutes here or there I've...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• What's the normal way machine-learning algorithms are integrated into normal programs?

  - by Benjamin Pollack

  I'm currently taking a machine learning course for fun, and the course heavily focuses on Matlab/Octave to write the code. One thing mentioned in the course is that, while Matlab/Octave are great for prototyping, they're very rarely used for production algorithms. Instead, those algorithms are typically rewritten in C++/Python/etc., using appropriate libraries, before reaching customers. Fair enough; I get that. But here's my question: is that done for cultural reasons, for technical reasons, or because there is really no language that provides Matlab/Octave-like fluidity, but in a compiled form that can be linked from C/C++/$MainstreamLanguage? The game industry uses Lua for game logic because it's easy to embed, and vastly superior for expressing things like AI. Likewise, there are Prolog variants for rules-heavy applications, Scheme variants for compilers, and so on. If there's a matrix equivalent language, what is it? If there isn't, why is this field different?

• Integrating Java webapps with Adobe Professional: Resources?

  - by Steve

  I'm interested in learning what resources there are for integrating Java and Adobe Professional, in general. If it helps, my projects already use the Spring Framework. My boss is particularly interested in being able to fill out a PDF form from within a Java webapp and have that data go directly to our database. She mentioned that .net had a lot of bridges to Adobe Professional. I would rather new projects be in Java so I am eager to find if there are any easy bridges between Java and Adobe Professional. Thanks in advance for any information. So far a Google search on "Java Adobe Professional" didn't turn up anything, so I thought I would ask here. Thanks.

• Game testing on Android - emulator or real devices?

  - by n00bfuscator

  I am working at a localization agency and we have been approached by a client about testing their games on iOS as well as Android. Testing on iOS seems fairly easy as we can just buy a couple of devices and we should be covered. For Android it seems to be completely different. From what i found, the emulator can cover all API levels, screen sizes and such, but i hear it's buggy and nothing could replace testing on real devices. With the vast amount of Android devices out there and the rate at which new devices are released it seems impossible to keep up. How can i test games (localization and functional) on Android covering all compatible devices?

• Calculating WPM given a variable stream of input

  - by Jaxo

  I'm creating an application that sits in the background and records all key presses (currently this is done and working; an event is fired every keydown/keyup). I want to offer a feature for the user that will show them their WPM over the entire session the program has been running for. This would be easy if I added a "Start" and "End" button to activate a timer, but I need to detect only when the user is typing continuously - ignoring all one-time keyboard shortcuts and breaks the user takes from typing. How in the world do I approach this? Is this even realistically & accurately possible?

• I want to record a screencast of a processing sketch

  - by nathanvda

  I have a created a music visualisation using Processing. I now want to convert that to a video, and the least obtrusive way I could think of is to record a screencast. I figured exporting Processing to video including audio, from within Processing itself, on ubuntu seemed an unsolved issue. Very hard and also could cause timing sync issues (since the music keeps running while images are captured). So move on to the screencast method. Dead-easy, I figured. But I was wrong. First hurdle was to find a way to record the sound from the audio (and not the mic). I did find a tutorial for that here. In short: use gtk-recordmydesktop and pulse audio. But, apparently, what happens: Processing does not use ALSA. When the sound is playing, it does not appear in the Pulse Audio mixer. How can I record the audio now?

• Auto save, filter applied screen shots

  - by DUKE

  Unlike Windows, it is very easy to take screen shots of selected area of the screen in Ubuntu. But I am researching how to have the following features when taking screen shots of the selected area: (1) The final output should be automatically saved to a location, for example on the desktop. (This feature is available in Mac OSX) (2) A filter (such as drop down shadow) should be automatically applied to the image. The above should happen as soon as the selection is done, without poping up any dialogs and expecting any inputs from the user.

• How to had operation with character/items on binary with concrete operations on C++?

  - by Piperoman

  I have the next problem. A item can had a lot of states: NORMAL = 0000000 DRY = 0000001 HOT = 0000010 BURNING = 0000100 WET = 0001000 COLD = 0010000 FROZEN = 0100000 POISONED= 1000000 A item can had some states at same time but not all of them Is impossible to be dry and wet at same time. If you COLD a WET item, it turns into FROZEN. If you HOT a WET item, it turns into NORMAL A item can be BURNING and POISON Etc. I have try to set binary flags to states, and use AND to set operation to combine different states, checking before if is possible or not to do it, or change to another status. Exist a concrete patron to solve this problem efficiently without had a interminable switch that check every states with everynew states? It is relative easy to check 2 different states, but if exist a third state it is not trivial to do.

• Collision detection in multiplayer games

  - by Bane

  This a followup to my previous question: How to implement physics and AoE spells in an MMO game?. There, we concluded that all physics have to be done on the server, and that I should use cylinders for calculations. Now, how can I check for collision detection on a ground-to-player basis on the server? It's fairly easy if the ground is a flat space, I just check if the player's z coordinate is lower than some value and voila, but, what if the map/ground itself is a model? How do I know where hills are on the server-side? How do I know when object collisions happen? I'm using node.js and socket.io.

• Update to Grub2.x broke Xubuntu 12.04 client in VirtualBox

  - by mikodo

  I have VirtualBox-4.1 installed in Ubuntu 10.04 with a .vdi running Xubuntu 12.04. Recently, a Grub update for Xubuntu 12.04 to Grub2.x, broke it with the following explanation: error: ELF header smaller than expected grub rescue _ Is there an easy fix for this? I could reinstall, but I tweaked Xubuntu 12.04 to my liking, and don't want to re-install a new .vdi. Unfortunately, I didn't make a snapshot of it. Google results, have been over my head. Thanks.

• Efficient way to calculate "vision cones" on 2D tile map?

  - by OverMachoGrande

  I'm trying to calculate which tiles a particular unit can "see" if facing a certain direction on a tile map (within a certain range and angle of facing). The easiest way would be to draw a certain number of tiles outward and raycast to each tile. However, I'm hoping for something slightly more efficient. A picture says a thousand words: The red dot is the unit (who's facing upwards). My goal is to calculate the yellow tiles. The green blocks are walls (walls are between tiles, and it's easy to check if you can pass between two tiles). The blue line represents something like the "raycasting" method I was talking about, but I'd rather not have to do this. EDIT: Units can only be facing north/south/east/west (0, 90, 180, or 270 degrees) and FoV is always 90 degrees. Should simplify some calculations. I'm thinking there's some sort of recursive-ish/stack-based/queue-based algorithm, but I can't quite figure it out. Thanks!

• Whats the Quickest and Cheapest Solution to setup a Affiliate Program for an Online Product?

  - by szahn

  I have a simple HTML landing page setup for an online product I want to sell. This product is a hardcover book. I want to be able to allow other people to setup their own landing pages and make a percentage of the sale from their site. What are some good payment processors or payment gateways that make setting up an affiliate system easy and fast? Clarification - When someone purchases an item, I want (whatever the payment processor is) to automatically route a percentage of that payment to the affiliate and the rest to the original author.) Are there any payment frameworks that already do this? I've found a few sites that let you do this, but they seem to restrict you to digital purchases only. However, my sites is selling a ship-able product and the affiliate system needs to support this.

• If I create a link to a folder, how can I get from that linked folder to the "real" folder from within Nautilus?

  - by snowguy

  Say I have a folder several layers down in my documents folder. And I want easy access to it from my desktop. To do that I: Go to the parent folder in Nautilus. Right click on the folder's Icon and choose Make Link Cut / Paste the new "Link to ..." folder onto my desktop. Great. And mostly this works fine for me. But suppose I want to get to that folder's parent. I can of course get there using the original path--what Nautilus calls the "link path" which I can see in the properties of the folder. But that seems harder than it ought to be. How can I click on the folder and go to the link path directly?

• SQL Server 2008 R2: StreamInsight changes at RTM: Event Flow Debugger and Management Interface Secur

  - by Greg Low

  In CTP3, I found setting up the StreamInsight Event Flow Debugger fairly easy. For RTM, a number of security changes were made. First config: To be able to connect to the management interface, your user must be added to the Performance Log Users group. After you make this change, you must log off and log back on as the token is only added to your login token when you log on. I forgot this and spent ages trying to work out why I couldn't connect. Second config: You need to reserve the URL that the...(read more)

• Alternative to Instant Form Pro

  - by TechDaddyK

  I was looking for a PHP form generator this morning and ran across "Instant Form Pro" by Joel Comm (http://www.instantformpro.com). It looks like it offers what I'm looking for (easy to use quick form generator based on PHP and MySQL that's self-hosted with no other fees), but the site smacks of "scam." It's being pitched as a way to generate surveys to increase your business, make lots more money, etc. Is this thing worth the $97 or is there an open source alternative that might be... safer?

• Multiple objects listening for the same key press

  - by xiaohouzi79

  I want to learn the best way to implement this: I have a hero and an enemy on the screen. Say the hero presses "k" to get out a knife, I want the enemy to react in a certain way. Now, if in my game loop I have a listener for the key press event and I identify a "k" was pressed, the quick and easy way would be to do: // If K pressed // hero.getOoutKnife() // enemy.getAngry() But what is commonly done in more complex games, where say I have 10 types of character on screen and they all need to react in a unique way when the letter "k" is pressed? I can think of a bunch of hacky ways to do this, but would love to know how it should be done properly. I am using C++, but I'm not looking for a code implementation, just some ideas on how it should be done the right way.

• Why do some open source projects do not allow to report issues in a public issue tracker?

  - by linquize

  Why do some open source projects do not allow to report issues in a public issue tracker? Those projects requires the issues to be reported via email, and the issues may be forwarded to people in mailing list. Users may repeatedly report the same issue if there is no public issue tracker, as they have no easy way to know what have been reported before. The project team members need to spend extra time answering those repeated issues. Some projects do have a public issue tracker, but the issues are still reported through email and they are posted only by the project team only after filtering. It does not allow anyone to report directly in issue tracker. (example: SVN) Such arrangement is not transparent nor open, which I think it violates the philosophy of open source. And it is outdated.
